7-zip access denied error when overwriting files in game folder (in program files)

Some users have been reporting an error something like:

`ERROR: Can not delete output file : Access is denied. : C:\Program Files (x86)\GOG Galaxy\Games\Umineko When They Cry - Question Arcs\BGM\system0.ogg`

I've seen this happen to a higurashi user, and two umineko users (one using GOG Galaxy).

Some things with this issue:
- running the installer again doesn't fix the error (it will fail every time)
- running as administrator doesn't fix the error (hopefully when this was done it actually made 7zip also run as admin mode)
- moving the game folder somewhere other than program files first did seem to solve the issue (only one person has tried this though)
- probably has to do with overwriting files in the 'program files' folder of windows

I would like to test some things on a windows virtual machine (add antivirus software, run as a non-admin user etc.) to see if I can reproduce the error, but I haven't done so yet.

Higurashi example error:
```
ERROR: Can not open output file : Access is denied. : c:\program files (x86)\steam\steamapps\common\Higurashi 03 - Tatarigoroshi\HigurashiEp03_Data\StreamingAssets\CG\sprite\normal\re2b_komaru_b1_1.png

Note that for umineko, currently there are only 3 files which fail to be overwritten:

- movie\umineko_op.mpg
- movie\umineko_op3.mpg
- BGM\system0.ogg (if using the bgm music patch)

Le problème concerne 7-zip qui ne parvient pas à écraser des fichiers dans les répertoires Windows Program Files en raison d'erreurs d'accès refusé. Commencez par examiner la logique d'extraction de fichiers du patcher, probablement dans un module gérant les appels 7-zip ou les opérations sur les fichiers. Reproduisez l'erreur sur une machine virtuelle Windows avec un antivirus et un utilisateur non administrateur pour comprendre les conditions exactes. Vérifiez comment le patcher gère les permissions des fichiers et les écrasements, et recherchez le code existant qui déplace ou supprime des fichiers dans les répertoires protégés.
